We were part of a consortium which designed and developed hybrid electric and battery electric research vehicles based on Jaguar Land Rover’s acclaimed Range Rover in a bid to reduce CO2 emissions and improve the vehicle’s performance.
The £16.3 million Evoque_e project saw research and development of hybrid electric and battery electric sport utility vehicles.
We were part of a consortium, which was led by Jaguar Land Rover, of nine industrial partners and two other universities.
In partnership with Jaguar Land Rover and Delta Motorsport, we developed brake and torque vectoring control systems to optimise energy recuperation during braking and enhance the handling performance of the vehicle.

Impact of our research
We were part of a consortium, led by Jaguar Land Rover, designing and developing innovative technologies in the field of vehicle electrification with a capability to make significant improvement in the performance of hybrid electric and fully electric vehicles, making them fun to drive.
These technologies were showcased by the creation of three research demonstration vehicles – a mild hybrid electric (MHEV), a plug-in hybrid electric (PHEV) and a battery electric vehicle (BEV).
In partnership with Jaguar Land Rover and Delta Motorsport, we led the development of brake control algorithms to maximise energy recuperation by blending hydraulic and electric brake systems. This was as well as developing torque vectoring control systems to enhance the handling performance of the vehicle by transferring brake / traction torque between front and rear axles and / or individual wheels.
The Evoque_e project was not only an ambitious development of three innovative technology research platforms, it was about the bringing together of like-minded organisations, passionate engineers and research scientists to deliver a common goal, of reducing CO2. Cranfield University, working alongside Jaguar Land Rover and Delta Motorsport, have developed the control algorithms not only for optimising energy recuperation, they have successfully exploited how to enhance the driver experience through torque vectoring and vehicle dynamics in electrified platforms.Mark McNally, Senior Manager, Low Carbon Vehicles
Why the research was commissioned
Jaguar Land Rover has been running a multi-billion pound programme since 2008 to reduce its CO2 footprint while ensuring its cars retained their luxury, performance, refinement and comfort. Having cut its CO2 emissions by 25% since 2007, it has been researching a range of technologies including battery electric vehicles and plug-ins to reduce this further.
The Evoque_e project was looking at a host of technologies including innovative hybrid and electric propulsion systems, integrated structures, power electronics, electric drives and energy optimisation.
We provided expertise in vehicle dynamics and electrified powertrain modelling, control and estimation algorithm development for active chassis systems, as well as rapid control system prototyping using a dedicated Hardware-in-the-Loop simulation facility.
In addition, we were actively involved in the control system implementation on different vehicle platforms, developing a flexible interface for our control algorithms. We also provided our expertise in vehicle instrumentation with GPS and inertial measurement sensors and planning of vehicle testing sessions.
Within the Evoque_e project, we expanded our Hardware-in-the-Loop simulation facility. This is now capable of supporting active chassis (steering and brakes), driver assist and electric powertrain control system development.
